Description
Technical field
The present invention relates to a kind of freezing, cold storage refrigerator electromagnetic sliding valve.
Background technique
Small refrigeration systems is used for freezing, the cold storage refrigerator of double temperature double control with two-position three way magnetic valve (standard No. is JB/T7223-1994), application 1 more than 0 year at home, this solenoid valve as shown in figure 13:
It has an import d1 and two outlets d2, d5;
Solenoid valve has an outlet d2 to be in normally off when the no electric circuit state, and another outlet d5 is in normally open, after the solenoid valve energising, often leaves a mouthful d5 and closes, and normally closed outlet d2 opens, by the open and-shut mode of power on/off switching solenoid valve two outlets;
The open and-shut mode of electromagnetic valve outlet is to realize its function by the working position of control electromagnetic valve spool d4, the no electric circuit state, spool d4 is in a working position under the effect of spring d6, close normally closed outlet, and another outlet is in normally open, after the coil d3 energising, electromagnetic force drives the pressure difference active force that spool overcomes spring force and air pressure, and spool moves to another working position, when this working position, normally closed outer pipe is opened, and often drives outer pipe and closes;
The driving mode of valve core of the electromagnetic valve is the direct drive-type of electromagnetic force, and spool moved with two end valve seats and directly clashes into when power on/off was switched, and can produce heavier Strike note in the handoff procedure;
Solenoid valve has a kind of working state to switch on always, arrives 4-6W though reduce the power consumption of solenoid valve as far as possible, and in actual use, the energy consumption of solenoid valve still accounts for the 4-6% of energy consumption of refrigerator.
Because the energy consumption and the impact noise of solenoid valve are bigger than normal, begin to adopt bistable electromagnetic valve to replace its application in recent years, as in No. 03271725.3 patent of ZL, disclosing a kind of two-bit triplet bistable electromagnetic valve, this solenoid valve has a normal open import and two outlets, two outlets are arranged on the left and right sides of valve core of the electromagnetic valve, by the left and right sides two ends action of pulse signal control electromagnetic valve spool in valve body, switch opening or closing of two outlets, and spool can be kept the steady state of spool two positions by being arranged on two outer permanent magnets of valve sleeve, so this solenoid valve only need expend certain energy in the moment of action, and can keep by the magnetic force of permanent magnet under normal circumstances, so the energy consumption of solenoid valve own is very little.
From functional characteristic, it is the same with the function that above-mentioned valve is realized, it mainly is the power consumption that has reduced solenoid valve, the spool action remains direct dynamic structure, impact noise has improvement slightly, working control only can make the Strike note sound control built in less than 55dB (A), and the noise of freezer compressor has been controlled at less than 40dB (A), and the action noise of solenoid valve can't satisfy the requirement of refrigerator.
Adopt freezing, the cold storage refrigerator of double temperature double control of two-position three way magnetic valve, the effect of solenoid valve is the circulating direction that switches through refrigeration agent behind condenser, the filter, typical link circuit such as Figure 14 institute in:
Solenoid valve often leave mouth → refrigerator evaporator → freezer evaporator → return compressor;
Normally closed outlet → the freezer evaporator of solenoid valve → time compressor.
For above-mentioned refrigeration system; because solenoid valve has an outlet to be in opening state all the time; all reach when temperature is set in refrigeration and freezer temperature; compressor shutdown; actual after compressor shutdown; also accumulating in the condenser has more refrigeration agent, and this part refrigeration agent is because solenoid valve has an outlet to be in open mode all the time, and refrigeration agent also can flow into refrigerator evaporator or freezer evaporator and continue evaporation.The true temperature of cold storage room or refrigerating chamber is lower than temperature is set, not only influence the accurate temperature controlling of refrigeration system, and the waste energy consumption, freezing, refrigerating box energy consumption increased.Therefore this bistable state two-bit triplet solenoid valve requirement not satisfied the high-performance of freezing, refrigeration unit and high energy saving and deposited.
Publication number has been for the Chinese invention patent prospectus of CN1388876A provides a kind of electromagnetic switching valve, make the high-performance of refrigerating and cold storage refrigerator and energy saving more height and deposit, this switching valve is provided with;
Valve pocket; Have with an introducing port of aforementioned valve pocket normal open, and with the valve chest of a plurality of export interfaces that are separated from each other the position upper shed of the planar bottom surface of aforementioned valve pocket;
With valve body is set with can turning round displacement in aforementioned valve pocket, described valve body with the aforementioned bottom surface opposing end faces of aforementioned valve pocket on, have the switch shape portion that aforementioned valve pocket and aforementioned export interface is connected disconnection, and by the revolution displacement connection of the aforementioned relatively export interface of aforementioned switches shape portion is disconnected to switch;
Drive the rotating electrodynamic type magnetizing exciter of aforementioned valve body with substep.
Further, aforementioned rotor and aforementioned valve body are by being positioned at epitrochanterian extension and being bonded cooperating of groove portion of being positioned on the aforementioned valve body, and gyratory directions is located mutually relatively.
And substrate is provided with the snubber of butt formula, by the extension of rotor and the butt of aforementioned snubber, limits the revolution displacement of aforementioned rotor, and sets the initial position of the gyratory directions of aforementioned rotor.
Yet, such scheme, for the switch shape portion that reaches its valve body can switch the connection disconnection of aforementioned export interface by the revolution displacement, need to guarantee the sealing of switch shape portion and described end face, and the factor of decision sealing effect, the precision that not only depends on described switch shape portion and end face itself, also depend on the assembly relation between the two, therefore just higher requirement has been proposed in processing, but, as Sealing, should select for use the material (as pottery) with good seal performance make as described in valve body and end face, this is again extremely difficult undoubtedly; And realization switch part shape is connected the structure more complicated of disconnection to valve pocket and export mouth, and the processing request of each member and assembly relation are each other had relatively high expectations equally.
And, be subjected to the structure influence of switch shape portion, on planar bottom surface, increase export interface again and have difficulty, be unfavorable for the open by design of valve.
In addition, valve body is when replying zero-bit, when the extension of rotor contacts with snubber with certain momentum, can be subjected to the reaction of snubber, thereby by turning to the static process that a gradual change is arranged, this process has multiple impact, although padded coaming has been installed on the snubber, but vibration and noise that bump produces are still bigger, and valve body still has apparent in view vibration, so performance also is not very desirable.
